Kill Them All - Sneak Peek - Spartacus plots a slave revolt, but will he be forced to kill Crixus before it can happen?

Spartacus was inspired by the actual slave of the Roman Republic who, in 73 BC, led a slave REVOLT that grew to more than 120,000 fighters. Defying the Roman Republic's legions of soldiers, they campaigned for two years through much of what is now Italy before succumbing to a much larger army. The series tells a new set of stories rich in character, action, sex and combat centered on the title character. As punishment for defying a Roman Legate, Spartacus is sentenced to die in the gladiator arena. But after surviving numerous fights, his sentence is commuted and he is sold as a slave to be trained as a gladiator.

Lucy Lawless (Xena: Warrior Princess) headlines a cast that includes Erin Cummings (Dollhouse), Peter Mensah (300, Avatar), Craig Parker (The Lord of the Rings Trilogy), John Hannah (The Mummy) and Andy Whitfield (later Liam McIntyre) in the title role.
